An open-​source volumetric gasmeter for lab scale fermentation processes

Biogas potential tests are the most relevant tests today to predict biogas production from biomass. They are often done using expensive equipment such as pressure sensors or small-​scale gas flow meter. In order to reduce costs and be able to have a higher number of replicates, it is necessary to provide research facilities with lower cost solutions without compromising precision of the measurements.

ReSource International has developed an open-​source system based on classical water displacement measurement. The system called #Bioklik is based on the open-​source Arduino board and operates automatically to measure a low flow of gas from fermentation processes. The #Bioklik system can also be used to monitor any other kind of fermentation process operated at laboratory scale with a continuous flow of gas such as brewing for example.
